Nadine Coyle said she has not spoken to her former Girls Aloud band mates for a couple of years, with the exception of Sarah Harding.
The Irish singer, 34, is one of the newly announced crop of 10 celebrities heading into the jungle on ITV’s I’m A Celebrity… Get Me Out Of Here! this weekend.
She told the Daily Mirror: “I haven’t seen or spoken to them since the end of Girls Aloud or just before I had my daughter. That’s about six years ago.
“Sarah more recently at the start of Big Brother”.
Harding was named the winner of Celebrity Big Brother in August 2017.
Mother-of-one Coyle said she was not sure if the former Girls Aloud band members – which included Harding, Cheryl, Nicola Roberts and Kimberley Walsh – would vote for her to do Bushtucker Trials.
She told the paper: “I’m not even thinking about it as a competition. I had to enter a singing competition to get into Girls Aloud whereas this is like who’s going to be the best jungler. Who makes the best fire, who makes the best water. I have no idea if they would vote for me.”
Girls Aloud was created during TV talent show Popstars: The Rivals in 2002.
The band went on to enjoy numerous chart and album successes before going on a break in 2009 and then splitting in 2013.
Ahead of her jungle stint, Coyle, whose daughter Anaiya is five, has admitted that her phobias are: “Heights, rats, snakes – everything!”.
Other celebrities heading into the jungle include American TV star Caitlyn Jenner, former footballer Ian Wright, TV presenter Kate Garraway and actress Jacqueline Jossa.
I’m A Celebrity… Get Me Out Of Here! starts on Sunday November 17 at 9pm on ITV.
